Description

[Detailed Description of the Invention] The present invention relates to a threshing device equipped with a straw binding device.

Conventionally, in the above-mentioned threshing device, in order to change the binding position of the threshed waste straw, since the direction of the waste straw when tied is constant, the installation position of the binding device is changed in the direction of the culm. However, the disadvantage is that the device becomes large due to the space required to move the binding device.

The present invention aims to make it possible to change the binding position while suppressing the increase in size of the device.

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, behind the threshing section 1, there is a waste straw conveying device for the threshed waste straw carried out from the threshing section 1 by a threshing feed chain 2, which is an upper side conveying device, and A waste straw tying device 3 is provided which ties together a certain amount of threshed waste straw supplied from this waste straw conveying device to the bundling space 3a, and releases the bundled waste straw by falling to the rear of the machine. A threshing device for a combine harvester is configured to perform the bundle release of the grains.

The waste straw conveying device is constructed as follows.

That is, as shown in FIG. 2, the waste straw from the threshing feed chain 2 is sandwiched between the protruding endless rotary chain 4 on the lateral side of the terminal end of the threshing feed chain 2, which is the upper conveying device. In cooperation with the rail 5, the aircraft is held and transported in the lateral direction, and the chute 6
A horizontal conveying device 7 is provided as a lower side conveying device configured to drop the waste straw in a horizontal state due to the sliding resistance of the waste straw and supply it to the bundling device 3 in a horizontal posture.

From the threshing feed chain 2 to the horizontal conveyance device 7
As shown in FIG. 3A and FIG.
The starting end of the action is located below the waste straw from the threshing feed chain 4, and the tip side of the waste straw is received on the upper side of the horizontal conveyance device 7 and guided by the sliding guide in cooperation with the stock side auxiliary guide 10. As shown in FIG. 3B and FIG. It is provided so that it can be freely switched to a second working state in which it is pressed and slidably guided on the lower side of the shaft. Further, a guide rod 9 that acts on the stock side of the waste straw from the threshing feed chain 4 in the supply path is extended from the action starting end of the clamping rail 5 so as to be rotatable and fixed. As shown in Figures A and 4A, the action start end is located above the straw being discharged from the threshing feed chain 2, and the discharging straw is moved to the side by the auxiliary guide rod 11. The first working state in which the grain is guided to the starting end of the horizontal transporting device 7 in a state below the transporting device 7, and the first operating state in which the starting end is guided from the threshing feed chain 2 as shown in FIGS. It is located below the waste straw, and guides the waste straw to the starting end of the horizontal conveyance device 7 in a state where the stock end is above the horizontal conveyance device 7 while holding the waste straw in cooperation with the auxiliary guide rod 11. It is arranged so that it can be switched to a second operating state.

In short, when the tip side guide rod 8 and stock side guide rod 9 are both set to the first operating state in which the tip of the waste straw is above the horizontal conveying device 7, the feeding posture of the waste straw to the binding device 3 is such that the tip side is tied. When the straw is in a horizontal position on the opposite side of the threshing feed chain 2 with respect to the working position, the head side guide rod 8 and the stock side guide rod 9 are both inverted from the first operating state. When the second working state is set in which the ears are located below the horizontal conveying device 7, the feeding posture of the waste straw to the binding device 3 becomes a horizontal racking posture in which the ears are located on the side of the threshing feed chain 2 with respect to the binding position. It's meant to be. In other words, by changing the mounting posture of both the guide rods 8 and 9 on the tip side and stock side, the posture of supplying the waste straw to the bundling device 3 is reversed to the above-mentioned horizontal rack posture, and the waste straw bundling is performed as bundling on the tip side. It is designed to switch to binding on the stock side.

In the above embodiment, the bundling device 3 is constructed in a fixed manner, but in order to expand the width of change in the bundling position, it is implemented in such a way that the bundling device 3 can be moved in the direction of the culm of the bundling waste straw. Good too.

In summary, the threshing device according to the present invention changes the posture of the waste straw at the waste straw transfer point between the upper side conveyor device 2 and the lower side conveyor device 7, which is provided on the waste straw supply path to the waste straw binding device 3. The threshing device is equipped with a posture switching device for switching from a horizontally racked posture to an upwardly facing posture, and the posture switching device is provided so as to be distributed on both sides in the direction of the removed straw culm at a clamping position in the upper conveying device 2. Each of the guides 8 and 9 has a guide surface formed at a position corresponding to the stock side and the tip side of the waste straw, respectively.
The guide 9 corresponding to the stock side is configured to be able to switch its posture between a posture of pushing up the stock side and a posture of pushing it down, and a guide 8 corresponding to the tip side is configured to be able to switch its posture between a posture of pushing down and pushing up the tip side. It is characterized by

In other words, the waste straw supplied to the bundling device 3 is placed in a horizontal racking position in which the tip side is on the side of the upper transport device 2, and in a reversed horizontal racking position in which the top side is on the side opposite to the upper transport device 2. Since it is switchable,
The binding position can be changed even when the binding device 3 is fixed, and even if a means for changing the mounting position of the binding device 3 is used in order to increase the width of change in the binding position, the displacement stroke of the binding device 3 can be changed. It is possible to secure the same width for changing the binding position while using less than before.

Therefore, it is possible to change the binding position while suppressing the increase in size of the device, and it is possible to construct a convenient device that is inexpensive and easy to handle and can change the binding position according to the post-processing of the bundled waste straw. It became.
